needs help for module ham in satellite.

Dear Sir;
Thailand Amateur Radio Satellites Corporate or TAMSAT GROUP needs help from
all ham interested in ham radio satellites. We offer ourselves to produce a
module to report the status of satellite of Space Affairs Bureau. (seen at
web: http://www.space.mict.go.th)
This modules works in basic packet radio system (same as DOVE DO-17
satellite). There would be a module to record sound and send back that has
a cycle of work in 1 minute as followed.
Time 00 – 20 second : send telemetry about the status of the satellite in
packet radio AFSK 1200 bps AX.25.
Time 21 – 40 second : record the received sound 20 second.
Time 41 – 60 second : send the recorded sound back 20 second.
and for all the process, using frequency at 145.825 MHz in FM
Our group would like to support about the circuit in the module together
with the knowledge in real production. Therefore this module would be
installed in the satellite of to travel in Space Affairs Bureau.
Please advice us for sample detail of circuit diagram , PCB , sample program
IC PIC packet radio for telemetry input ASCII 9600 bps to output 1200 bps
AFSK AX.25 , other detail and reply back to
